McKeag, Ridgewood, NJ., assignor to AutographicBusiness Forms, Inc., South Hackensack, NJ., a corporation of New JerseyFiled Feb. 1, 1965, Ser. No. 429,492 3 Claims. (Cl. lill-93) Thisinvention relates to an improved method of printing checks, depositslips, and other business and like documents.

This application is a continuation-in-part of my copending applicationSerial No. 125,029, filed July 3, 1961, which in turn is acontinuation-in-part of my copending application Serial No. 21,313,tiled April 1l, 1960, now abandoned.

Atl the present time, it is customary to base print a supply of checksand like documents with the name of a bank and other indicia which iscommon to all checks in use by such bank, and later to print limitedquantities of such items with indicia such as the name, address, and theaccount number of an individual bank customer. This has been doneconventionally by locking up in a press chase rigid type or printingplates made therefrom relating to the individual bank customer, then,printing the number of checks required, for example 100 units, and thenremoving the type or printing plates from the chase of the printingpress and inserting newly prepared type or plate material required byand related to the next bank customer. It is not practical, however, bythis conventional printing and preparatory method, to producepersonalized and account numbered checks or deposit slips in quantitiesless than 100 units because of the cost of the preparatory work and thepress make-ready in relation to the quantity of documents producedtherefrom and for the reason that the manufacturer must set the sellingprice of the product and service so produced higher than the purchaserwill pay. However, there exists a great demand for such small quantitiesof personalized and account numbered bank documents. Up to the presenttime, this demand cannot be satised.

An object of this invention is to provide an economically practicalapparatus for personalizing and account numbering of any quantity ofchecks or deposit slips in multiples of ten units, for instance, withthe minimum quantity to be ten units.

It is a further object of this invention to eliminate the need for allconventional preparatory work common to conventional printingmethodology such as typesetting, proofing, platemaking, and pressmake-ready. As will be seen in the disclosure to follow, this objectivehas been met without the usual wastage of type and/or printing platematerial common to conventional printing methodology resulting from thenecessity of changing from one press make-ready to another uponcompletion of the small quantity of personalized and account numberedbatch run and without the necessity for preliminary typesetting,proofing, and platemaking.

Another object of this invention is to avoid the necessity forinterrupting the printing process for the purpose of making the typechange required upon completion of 'one small batch quantity run to thestart of the next.

A yet still further object of this invention is to provide a lpracticalmechanically and electronically controlled mechanism whereby Wheelsbearing on their periphery the alphabetic and numeric characters areautomatically set up according to predetermined instructions toelectronic storage and memory units forming an integral component partof the equipment represented by the invention, in less than ten secondsof time and once so set 3,215,069 Patented Nov. 2, 1965 optically,magnetically, or electrically sensed for the purv pose 'of sorting,routing, and identification with the customer as by bank number, branchnumber, or account number respectively.

For this purpose, certain areas are designed to receive the respectiveindicia and certain standardized characters known as Magnetic InkRecognition Characters, numeric in format,are used, and these, havingbeen imprinted with magnetic ink, may be sensed by automatic equipmentand be translated thereby into various kinds of actions or responses inmachinery such as sorting, computing, and/or high speed data processingmachines. However, such indicia, for the purpose required by the banks,must be unique to each bank customer separately and different fromrequired indicia for each other bank customer.

What has been said about bank checks applies also to deposit slips andother documents which must be identied with one customer and onecustomer only. In the majority of cases, each bank customer requiresonly small quantities of documents such as deposit slips for use over aperiod of many months. To obtain such small batch quantities, eachdifferent from all others, is a problem solved by this invention. Here,again, the

deposit slips and other pieces are preprinted in large quannecessity offeeding such workpieces one by Ione to a' printing press.

To do this according to the present invention, the checks or otherpieces are printed in continuous form with the standard indicia, andwhile stillv in such form are after-printed seriatim by one or moreprinting units. The printing units may be provided with the usual fontof characters or with special characters and the printing may beperformed with ordinary and/or special ink or transfer materialaccording to the requirements. Thereafter, the continuous strips aresevered into separate checks or pieces and are stacked and bound fordistribution and use. The after-printing is preferably performed bysettable Wheels carrying on their peripheries letter and/or numberand/or symbol type faces.

According to the present invention, the after-printing for each kind ofworkpiece is controlled by a prepared card such as a tabulating cardhaving punch holes sov positioned that when presented to an interpretingor sensing mechanism they will control the setting of the printingwheels in one or more printing units and determine the number of checksor pieces to be after-printed. The cards for the various kinds ofworkpieces are stacked so that after the wheel setting is performedaccording to one card the next card is presented to the scanningmechanism.

In the perferred form of my invention, the continuous strip isaccurately and positively advanced intermittently to the printing unitor units by a longitudinal row of feed perforations usually in onemargin of the strip engaging` suitable pin bearing devices such as awheel or belt. The feeding operations of the strip may be controlledcoordinately with the operations of printing units so that the strip ofWorkpieces is stationary while the after-printing is being done.

Thus it is merely necessary, according to this invention.

for the printer to have on hand a supply of preprinted checks or pieceswith indicia general to all accounts and a punched card for each accountand use the latter when filling an order for personalized checks or areorder thereof at any time.

According to the present invention, the position of the linesy ofafter-printing on the checks may be controlled by adjusting the printingunit or units longitudinally along the path of travel of the strip, orby forming a loop in the web between adjacent printing units. Thus theimprints may be located in any desired position of a check for instance,from the uppermost transverse margin to the lowermost.

The printing units may include a printing wheel for each letter-spaceacross the check and therefore the after-printing may be done on anyplace on the check from one edge to the other.

In many cases only a single ply preprint strip is afterprinted. However,in the other cases, particularly deposit slips, it is desired to haveseveral copies of each transaction and, therefore, the strip will bemulti-ply.

Other features and advantages will hereinafter appear.

In the accompanying drawings:

FIGURE 1 shows a continuous strip of workpiecesv printed according tothe present invention and before the workpieces have been severed fromthe continuous strip.

FIG. 2 is a view like FIG 1 but shows superposed continuous strips toprovide a plurality of sets of assembled workpieces.

FIG. 3 is a schematic view of apparatus that may be employed forprinting strips of checks or the like, such as the strip shown in FIG. 1according -to one form of the present invention.

FIG. 4 is a fragmentary view showing apparatus whichk may be used forprinting and assembling the strips shown in FIG. 2--only theintroductory andl delivery ends of the apparatus being shown, theintermediate portions being the same as in FIG. 3.

FIG. 5 is a detail sectional view showing the belt for feeding thecontinuous strip and the driving means therefor.

As a prerequisite to operation of the apparatus of this invention, it isnecessary first to print by conventional means a large supply ofcontinuous strips, such as `the strip shown in FIG. 1 which contains asuccession of printed checks having indicia which is common to theindividual checks of many kinds for instance, the name of the bank andother indicia such as shown. The continuous strips of checks are storeduntil needed.

Thereafter it is necessary to prepare a printing control card, such as atabulating card, having punch holes indicative of specific indiciarelating to a particular customer or account and indicative of thenumber of checks to be printed successively for that customer oraccount.

A similar control card is prepared for each customer or account andthese are stacked in a card-sensing unit indicated by the referencenumber 11 in FIG. 3. Any suitable card-sensing unit, such as :thosedisclosed and described in detail in the patents to Daly, No. 2,531,873,issued November 2S, 1950, or Nolan, No. 2,770,188, issued November 13,1956, will 4suffice to sense the necessary items of data from the punchcards and transmit this data to printing units. The continuouspreprinted strip 10 is then fed into an auxiliary printing machine 12having a plurality of printing units one for each line to be printed.

FIG. 3 is a schematic view in which there are shown two printing units13 and 14 to which the preprinted strip 10 may be fed to receive theafter-printing as controlled by the. punch cards. These printing unitsmay be of the type disclosed and described in detail in the patent toRabenda, No. 2,569,829, issued October 2, 1951, either as disclosedtherein or as modified to operate in the manner disclosed and describedin detail in the aforementioned Daly patent in which an impressionmember strikes the strip for effecting printing contact with the typewheels rather than shifting the type wheels relative to a stationaryplaten as disclosed in the Rabenda patent. The end of the strip 10 maybe taken from a supply roll 15 and may be guided through the printingmachine 12 by a paper table 16. Preferably the feeding of the strip iscontrolled by marginally punched holes 17 therein which engagepin-carrying feeding bands 18 and 19. The strip 10 is advancedstep-by-step at check-length intervals by intermittently operatedfeeding means 20 which is under the control of the card-sensing unitthrough a lead 20a and is initially placed on the yfeeding band 18 sothat the line of the check to be imprinted will register with theprinting elements of the printing unit 13 when the strip comes to rest.It is preferable that both printing units 13 and 14 operatesimultaneously, and in order that the line of print from the unit 14 mayfall on the desired printing line of the check, the apparatus isarranged so that the relative position between the check tobe printedandthe printing unit 14 can be varied.

This may be accomplished as shown in FIG. 3 by providing a loop 21V inthe strip between the printing units 13 and 14 and regulating the lengthof the loop so that the position of the check to be printed by the unit14 can be advanced or retracted when threading the web through theVprinting machine to cause the line of print and the printing line tocoincide. The extent of the loop may be controlled by a pin wheel 22adjustably carried in a slotted bearing plate 23.

The printing units 13 and 14, as seen in the aforementioned Rabenda orDaly patents, are preferably of the type comprising a row of wheelsbearing type faces on their peripheries and suitable mechanism, operatedin response to signals transmitted through leads 11a and 11b, toposition the type wheels under the control of a punched card so that ateach operation of the printing units 13 and 14 a single lineof typeimpressions is made by each of the printing units. When the type wheelsare positioned, impact devices 13a and 14a, such as those disclosed inthe aforementioned Daly patent function to cause ink carried by the typefaces or transfer material carried by an interposed ribbon to print thelines on the check. After the first and second lines, in the examplegiven, have been printed on the check, the feed mechanism may advancethe strip of checks one check-length and bring the next checks intoposition to be printed.

As illustrated in FIG. 433, the impact `devices 13a and 14a may becaused to operate simultaneously, for example, by meansv of a momentarycontact switch 40 which is actuated by a cam 42 mounted on a shaft 44which is driven continuously by the same infeed power that drives theintermittent feed means 20. The cam 42 is driven in timed coordinationwith the cycling of the intermittent feed means 20 so that the switch 40is actuated during the instant that the strip 10 is not moving. Theswitch 40 is effective to actuate the impression means 13a and 14asimultaneously through the leads 46 and 48.

According to the present invention, the continuous strip is separatedinto individual checks which may be As indicated above, the number ofchecks to be printed is also controlled by the punched cards, and thismay be accomplished by having the punching on the card control adescending totalizer for each printing unit operated by the impressionsmade by its printing unit so that if twenty checks of the same kind arerequired the descending totalizer will be set for twenty and when itreaches Zero it will temporarily interrupt the operation of the printingunit.

Again referring to FIG. 3, each printing unit 13 and 14 has associatedtherewith a descending totalizer 13b and 14b, each totalizer beingeffective to be preset to determine the number of checks to be printedby its corresponding printing unit, and also effective to interrupt theoperation of the feeding tractors 18 and 19 and the impression means 13aand 14a such as by each totalizer consecutively interrupting theoperation of the infeed power means for the intermittent feed mechanism20 and the impression means actuating cam 42. Thus it is seen that'eachtotalizer is connected to its corresponding printing unit by a lead 13e`and 14e` respectively which, by way of example, energizes the totalizerto descend from a preset quantity by one unit each time that thecorresponding impression means is actuated. When the totalizers reach azero setting, they actuate switches 13d 14d respectively, each of whichis effective to interrupt the operation of the power means for theintermittent feeding means 20 and the impression means actuating cam 42through leads 13e and 14e respectively. Each totalizer is also providedwith a resetting motor 13f and 14f respectively by which the totalizersare reset in response to signals received from the card sensing unit 11through leads 13g and 14g respectively. The construction of thedescending totalizers is disclosed and described in detail in theaforementioned copending application Serial No. 125,029.

The data interpreting machine 11 Within which the punch cards are placedis set up so that after the printing wheels have been set on each unitby signals through leads 11a and 11b, the setting remains locked. Thecard sensing unit 11 is effective to commence operation of the apparatusin response to a signal through lead 20a, and simultaneously printing byboth printing units continues until the desired number of impressionshas been made by the printing unit 13, at which time the totalizer 13bstops operation of the apparatus. At this point the next card ispositioned by the card sensing unit 11 to be sensed to unlock and causeanother setting and relocking of the type Wheels .of the printing unit13 and another setting of the descending totalizer 13b in accordancewith the indicia lon the next punch card for the next group of checks tobe printed. Upon completion of these settings and relocking of the typewheels, the card sensing unit commneces operation of the apparatus tocause printing until the printing unit 14 -has completed printing theindicia individual to the first group of checks as indicated by thetotalizer 14b, at which time operation lof the apparatus is againinterrupted. The card sensing unit 11 is then effective to unlock andcause another setting and relocking of the type wheels of the printingunit 14 and another setting of the totalizer 14b in accordance with theinformation from the second punch card, and is thereafter effective toresume operation of the apparatus to continue the printing of the secondgroup of checks until the totalizer 13b again reaches its zero setting.This cycle of operation is repeated until there are no further punchcards to be sensed.

Thus, by successively setting the printing units, no loss of checks willbe incurred by the change over-from one kind of check to another.

According to the present invention, one of the printing units 13 or 14has on its type wheels printing characters which are specially formedfor magnetic ink character recognition and the other unit may have typefaces or ordinary characters. Thus, in the examples shown in FIG. 1, thename and address of the bank customer may be printed as at 26 inordinary type with ordinary ink lor ink ribbon, while the branch andaccount number indicated at 27, ABA bank number indicated at 23 and therouting for bank clearance purposes indicated at 29 will be printed withmagnetic material so that those items can be sensed on a magnetic inkcharacter recognition machine. It is a matter of choice and conveniencewhether the magnetic characters are printed by the unit 13 or by theunit 14.

It should be understood, of course, that while in describing theapparatus of this invention, bank checks are referred to, the apparatusmay be used for other purposes where a preprinted form is to haveafter-printing made thereon in limited quantities, and in thisconnection one such different use is that of preparing bank depositslips in limited quantities. The apparatus as it applies to such usewill now be described in connection with FIGS. 2 and 4 of the drawings.

In this embodiment of the invention, the workpiece includes an originalcopy strip 30, a transfer strip 31 and a copy strip 32, and ifadditional copies are required extra transfer and copy strips may beprovided. As shown, these are prepared in continuous form and containindicia which is common to the individual deposit slips of many kinds,for instance, the name of the bank and other indicia such as shown.

The continuous strips are preferably in separate packages such as rollsor zigzag packs, and when needed the strips are guided to the auxiliaryprinting machine 12 where the record and copy sheet is aligned by pinWheels and the transfer strips are adhesively secured together bymechanism 33 at the margin to make joined sets of strips. The continuousstrips are fed over the paper table 16 and their feeding movements arecontrolled by marginally punched holes 17 in the strips which engagepin-carrying feeding bands 18 and 19 as in the form of the inventionshown'in FIG. 3. The feeding and imprinting operations are performed inthe same manner as referred to in connection with FIG. 3, the printingunits 13 and 14 successively operating on the pile of strips, theoriginal strip being printed by ink applied to the printing Wheels orthrough a transfer member and the copy strip having the same indiciaprinted on it through the medium of the interposed transfer strip.

The other aspects of operation are the same as described above inconnection with FIG. 3, but the end product in this situation is aplurality of groups of deposit slip booklets all of the same kind andidentified with a particular customer or a particular account, each topsheet of the booklet having the preprinting, one line of after-printingin ordinary type, and the other line of after-printing with magnetic inkcharacter recognition type.

Thus it will be seen that the present invention completely obviates lthenecessity for preliminary and preparatory Work such as typesetting,proofreading, platemaking and make-ready which would be required byprevious methods of after-printing checks and the like.

By employing settable type-carrying wheels and locking means therefor,the printing characters are automatically positioned in perfectalignment for the precise requirements for printing operations. This isan important consideration in connection with mechanized check handling,otherwise referred to as magnetic ink character recognition, and thusthe apparatus of this invention is able to fulfill standard requirementsset by the American Bankers Association as standard practices which areincreasingly coming into universal use in the banks of this country. Therequirements so laid down are of such a precise nature that they cannotbe met by normal pr1nting equipment. The apparatus disclosed hereinmeets these strict and precise requirements on a fully automated basis:and in a practical and economical manner and at a substantially lowercost.

Variations and modifications may be made within the scope of the. claimsand portions of the improvements may be used without others.
